Overview
The Luna FPS-001 is a small, piezo-driven phase shifter that shifts or modulates optical phase by stretching a length of fiber. It provides phase shifts of several π at frequencies from DC up to 20 kHz.
Because the optical path is entirely in fiber, the device has minimal insertion loss and return loss. The FPS-001 uses a straight fiber rather than fiber wound on a frame, so the optical path length in fiber equals the length of the device from connector tip to connector tip. This length can be minimized by controlling the pigtail length or by choosing the NoTail version.
The FPS-001 is suited to small-range phase shifts, either for fine phase adjustment or to add a dither in interferometric setups such as fiber interferometers, fiber resonators and fiber laser systems.
